The three minute film was uploaded to YouTube yesterday and has so far attracted more than 130,000 hits.

The film states that people are half as likely to be invited for a job interview if they have a black sounding name.

It claims black people are likely to pay $700 more for a car and will be shown around nearly 18 per cent of homes on the market when looking to buy a house.

A number of other studies are also used in the film to say that black and white people use marijuana at similar rates, but black people are four times more likely to be arrested and six times more likely to go to prison.

Political parties did not respond to questions from people with black sounding names, the film claims.

Hundreds of rioters looted stores, set buildings on fire and injured at least 15 police officers on Monday. The violence, which had followed a week of peaceful protest, broke out following Mr Gray's funeral.
